Which one among the following statements for the gases mentioned below is not correct?

Correct option is B

The correct answer is (b) Helium is a commonly used gas in electric bulbs. Helium is not commonly used in electric bulbs; instead, argon is the most commonly used gas in incandescent light bulbs. Argon, being inert, helps prevent the tungsten filament from oxidizing and burning out quickly. Helium, although also an inert gas, is more commonly used for balloons and in cryogenics, where its properties are more advantageous. Therefore, the statement about helium in electric bulbs is not correct.
Information Booster: ● Hydrogen has three isotopes: protium (¹H), deuterium (²H), and tritium (³H). ● Helium is used for applications like filling balloons, cooling superconducting magnets, and in nuclear reactors, but not in electric bulbs. ● Oxygen is indeed used as an oxidizer in rocket fuel, providing the necessary element for combustion in spacecraft engines. ● Nitrogen is commonly used in food packaging to replace air, as it helps to prevent oxidation and spoilage of the food by displacing oxygen. It is also used to maintain freshness and extend shelf life.
